Default 125 AMP Nissan quest alternator upgrade

Okay guys, I ordered the 125 AMP quest alt from a 93-97 quest.



maybe this helps more



old and new

1. Drill out the bottom 2 mounting holes to the size of the bolt. My bit didn't have a size so I dunno the size.


2. Change out the pulleys. The serpentine pully can be trashed bc it is no longer needed. Behind the bolt you need a lock washer.




3.the BACK of the FRONT lower mounting bracket needs grinded down 1/4 inch to make the pulleys line up. Make sure to put spacers or washers in the back to keep it stable.

(couldnt get pictures of the washer behind it)



4. Take off the fan, and loosen the altenator adjustment bracket. This will allow you to slide the top of the altenator behind it bc the top post is thicker than stock.


(kinda a weird angle but it fits in there pretty good..)

5.you will also need a longer v belt 2 sizes bigger from the stock wich is a 70 to an 80

when you put a audio system or compressors are taking to much of the amperage and also if your lights dim while your compressors are in use

this is a very cheap and affordable high output alt. If mine goes out im defiantly going this route.
